Why Is Gel Used During Ultrasound Scan?

Before conducting an ultrasound scan your doctor will apply a clear, water-based gel to your skin. This helps provide accurate images for several reasons.

Better Contact

• Applying a gel to the skin during an ultrasound procedure allows the transducer to pass over the skin more easily so that it makes better contact with the body.

Sound Waves

• During an ultrasound the transducer emits high-frequency sound waves to obtain images of the inside of the body. Using a gel during the procedure allows them to pass through with little interference.

Air-Free

• Air bubbles contained in the gel can result in cloudy images. Only gels manufactured for medical imaging should be used for this process.

Dermatology-Tested

• The gel should not contain anything, including sensitizers and fragrances, that might irritate the skin or cause a reaction.

Clear Image

• Using the proper gel during an ultrasound procedure helps provide a clear image of the area of concern. This enables your doctor to form a more accurate diagnosis.
